Title (EN) FLUID SWIVEL CONNECTOR
(FR) RACCORD PIVOTANT POUR FLUIDE
Abstract:
(EN) A connector arranged for high pressure fluid carrying conduits comprises a central core (1) having at least one fluid passage such as an integral bore (31), formed therein and an outer member surrounding the central core and being moveable relative thereto. The outer member comprising at least one segment (55) having a fluid flow conduit and sealing means for the connector junction comprising an intermediate member, at least one static seal for non-moveable surfaces and at least one dynamic seal for relatively moveable surface. A plurality of segments may be stacked on top of each other and held together by the application of a compression force on shoulders of the segments. A relative rotational capability is preserved for the parts of the connector yet a more reliable and versatile connector is achieved in which the modular construction allows a variety of sizes to be offered more easily and cheaply and engineering tolerances can be more easily met than with a single piece construction.
(FR) Raccord conçu pour des conduits transportant des fluides haute pression et comprenant une partie centrale (1) pourvue d'au moins un passage pour fluide tel qu'un alésage intégral (31) et un élément extérieur entourant la partie centrale et pouvant se déplacer par rapport à celle-ci. L'élément extérieur comprend au moins un segment (55) pourvu d'un conduit d'écoulement de fluide et un dispositif d'étanchéité destiné au raccordement du raccord comprend un élément intermédiaire, au moins un joint d'étanchéité statique destiné à des surfaces fixes et au moins un joint d'étanchéité dynamique destiné à une surface relativement mobile. Une pluralité de segments peuvent être empilés et maintenus ensemble par application d'une force de compression sur leurs rebords. Avec cette construction, les pièces constitutives du raccord peuvent tourner les unes par rapport aux autres, et on obtient un raccord plus fiable et polyvalent. Sa structure modulaire permet de proposer plus facilement et de manière économique une variété de dimensions, et peut satisfaire plus facilement aux tolérances mécaniques qu'avec une structure monopièce.
